Sergio Ramos might be an excellent defender, but discipline hasn't been one of his strong suits.

Having received a club record 19 red cards during his nine-year career at Real Madrid, the 28-year-old was up to his old tricks again during the first leg of Real Madrid's Spanish Super Cup tie with Atletico Madrid.

After being flattened by Mario Mandzukic during an aerial duel, Ramos appeared to exact a little revenge with a sneaky little jab to the Croat's face as he tried to get up.

While the Spaniard tried to brush it off as an accident, it's hard to give Ramos the benefit of the doubt with his history of ill-discipline.

Watch the clip above and see for yourself if Ramos intended to punch Mandzukic or not.
